"Sierra are you sure about this?" Kai asked one last time as Sierra nodded.
Kai then put the crown on his head as a black glow slowly surrounded his body. He closed his eyes as he slowly started levitating in the air and Sierra could only look at him with a smile.
A wave of power went around the room as Kai's clothes turned to pure black. He opened his eyes and they too had turned black in color though only his irises had turned black.
His hair also slowly turned pure black as he landed on the ground with the crown hovering over his head. Then with a flash, his appearance changed back to normal as the crown stopped glowing.
"Congratulations Kai, you are now the elemental ruler of dark." Sierra said while clapping as Kai remained silent.
"Sierra, you were actually a spy?" He slowly asked as Sierra's eyes turned sad and her body started shimmering.
